A genius? I just love studying.

Chapter 38 Full marks?

"Really?"

Liang Peixuan's eyes lit up, and he suddenly felt that the golden cheesecake in his hand smelled fragrant again.

If that is true, then he got all the fill-in-the-blank questions right. Although he did not do well on the big questions, he did get the first and second questions right, so he got 80 points in total.

If nothing unexpected happens, the second place will be secured!
puff!

A laugh broke the silence of the classroom.

Zeng Jian had not intended to laugh. Even when Chen Hui said that, he just rolled his eyes and cursed in his heart, "What a waste of money."

But when he saw the joy on Liang Peixuan's face, he really couldn't help it.

Sure enough, where there are crouching dragons, there must be phoenix chicks.

This guy actually believed a guy who handed in a blank paper two hours in advance.

Is his happiness serious?

The classmates surrounding Zeng Jian all had smiles on their faces, and the others were also a little amused, as they were really amused by the two of them.

But they didn't notice that when Chen Hui said that, the expressions of the people headed by Deng Leyan became serious. They looked at each other and saw surprise in each other's eyes.

That guy handed in his paper two hours early. They originally thought that he had really handed in a blank paper as Zeng Jian said, but now it seems that this may not be the case!
This guy is probably not some poor student who is just filling in the gaps, but a real master!
Because the answer they got for question 8 was also 591!

But they really couldn't understand. Since this guy was not incapable of doing it, why did he hand in the paper two hours in advance? Wasn't this a waste of opportunity?
If he had taken the three-hour exam, his final score would probably not have been worse than theirs.

Because it was too absurd, another guess involuntarily emerged in their minds.

Could it be that he really finished the entire test in just one hour?
However, because this guess was even more ridiculous than the previous one, they quickly pulled it out of their minds and threw it into the trash can.

Deng Leyan had never been one to speculate. After a brief hesitation, he stepped in front of Chen Hui and asked, "How did you solve question eight?"

The eighth fill-in-the-blank question is not difficult, but it is very time-consuming and requires the use of classified enumeration. When you think about the number 591, you will know how much work the enumeration requires.

And if you are not careful, you will miss something.

Even for him, it took more than ten minutes to make it.

But this guy in front of me probably only took less than five minutes!
He and Chen Hui were taking the exam in the same classroom. Although he didn't see Chen Hui doing the test papers, he could hear the sound of flipping the test papers in the quiet classroom.

At that time, he thought Chen Hui had given up on the eighth question, but he didn't expect that the other party had already solved it.

Such a fast problem-solving speed must not be classification enumeration.

He was very curious about the other person's approach to solving the problem.

"???"

Deng Leyan's action immediately made the classroom quiet again.

Zeng Jian's face turned a little red.

The students who were laughing happily just now now look unhappy.

Because, Deng Leyan's question means that his answer is also 591, the same as that of the guy who handed in the paper early!

They may suspect Chen Hui, but they will not suspect Deng Leyan.

Last year, when he was in the third grade of junior high school, Deng Leyan got full marks in the provincial competition.

His answer is the standard answer!
If the answer to question 8 is really 591, then...

"Category enumeration."

Chen Hui frowned. He didn't like being disturbed when he was reading.

"impossible!"

Deng Leyan also frowned. "How could we solve it so quickly using classification and enumeration?"

"How hard can classification and enumeration be?"

Chen Hui really didn't understand. When he saw the question, he already had an idea in his mind. After calculating it on a piece of scratch paper, he naturally got the answer.

So, is this question difficult?

Deng Leyan stopped talking and turned away silently. In his opinion, this guy probably didn't want to tell him that unique solution.

But this is understandable, as others have no obligation to preach to him or answer his questions.

"But, besides classification and enumeration, how else can we solve Problem 8?"

Deng Leyan returned to his seat, the eighth question popped up in his mind, and his brain began to work rapidly.

"Did that guy really only get 50 or 60 points in math on the high school entrance exam?"

After this incident, the classroom became much quieter and everyone's discussions became much quieter.

"I've been in the same class with him for three years, how could I not understand him?"

Zeng Jian's expression had returned to normal. He had figured out the key. "Don't be fooled by him, everyone. If he really could do it, if he really understood math, how could he possibly say something like, 'How difficult can classification and enumeration be?'"

“Who knows what answers he wrote on the test paper.”

After hearing this, many people suddenly realized.

Because even if that guy didn't get 50 or 60 points in math in the high school entrance exam, it would be too outrageous to hand in the paper two hours early.

In comparison, they would rather believe what Zeng Jian said than believe that anyone could finish this set of test papers in an hour.

Department 307, School of Mathematics, Chengdu University.

The room of about 50 square meters was divided into two parts.

On the right side of the entrance are three rows of tables, each with a computer and a chair. They are no different from the workstations in a company and are where students study and research.

On the left is a long table, which is usually used as a small meeting room in the laboratory. If anyone has any good ideas, they can have a quick meeting here to discuss them.

Now the table is full of people, each with a stack of test papers in front of them, and everyone is concentrating on correcting them.

The work of marking the papers is not difficult. As long as the answers to the eight fill-in-the-blank questions are correct, you can get points. As for the big questions, most people only do the first two, which directly reduces the workload by half.

Everyone here is either a graduate student or a doctoral student in the mathematics department. These questions are not too difficult for them, so it is naturally easy to correct them.

But marking papers is undoubtedly boring.

This revision work may seem casual, but the standards are still very high.

The test papers are all covered with names, and not only do they need to be scored double-blind, but there are also two secretaries from the mathematics society standing by to watch. Finally, the score of each test paper needs to be reviewed and confirmed by the team leader.

"Tsk tsk tsk... This kid even got the first big question wrong. That's too bad."

This group of graduate students and doctoral students made comments while revising the work.

"What's that? My friend got all three of the questions right, but got four of the fill-in-the-blank questions wrong. God knows how he did it. That's what's so miserable!"

He could see that this student was capable, but unfortunately he made too many mistakes in the simple fill-in-the-blank questions. Otherwise, this student would have been able to compete for the provincial first place.

“This year’s questions are still too difficult!”

"Forget about getting full marks. I can't even find a few people who can complete the third question."

"Last year, we had a lot of full marks, but what's the point? In the end, no one made it to IMO. It's worse than it is now."

"But it's too difficult. I'm afraid the little ones will be hit hard this year."

"Only by correcting a wrong can one go too far."

"I have a perfect test paper here!"

Suddenly someone said, and he looked up at Li Bin and Yan Zhenhua, who were staring at each other and arguing with each other, "I heard that someone handed in their paper two hours early today and still got full marks. I wonder if it's this one?"
